General
Reaching a length equal to the height of an average adult magi, krotalos are one of the larger venomous snakes. They rarely bite, however; instead they use their rattle to put their prey, or any creature foolish enough to try and harm them, into a deep sleep that can last anywhere from a few hours to a few days. As there is no known cure for this comatose state, it is wise for magi to be extra mindful of their surroundings as this could mean death if traveling alone. Many healers - using special earmuffs to block the sound of the rattle - will milk the venom, for it is used in many powerful potions. When a krotalo sheds it's skin, their colorful scales are collected and sold to be made into jewelry.
Egg
This scaly egg has a small tail poking out of it.
Hatchling
Krotalo hatchlings may be small, but they are still dangerous. While their rattles are not large enough to put anything to sleep, they make up for that with powerful venom. One bite is enough to put down a fully grown rekantum in a matter of minutes and an adult magi in seconds. For this reason, many creatures have learned to stay away, though some birds of prey will make a meal of one if they can by using their thick feathers to block the krotalo's fangs.
Adult
Adult krotalos, when they are not hunting, spend most of their time basking in the sun. Their coloration blends perfectly into their surroundings such that you would never know one was there unless it moved. Though not particularly friendly, if raised from an egg, they will bond with the magi who raised them and allow themselves to be held. Wild krotalos, on the other hand, can never be tamed. As they age, their venom becomes less potent as they rely on it less. A bite from an adult krotalo will make a magi deathly ill, but with proper treatment, the magi will survive.
